Start with safe basic checks
Pause the cycle and follow the manufacturer instructions before opening any service flap. Water can be hot and may spill quickly.
Step 2
A kinked drain hose or a blocked user-cleanable pump filter is common. Keep towels and a shallow tray ready if the manual permits filter cleaning.
Step 3
Persistent humming, repeated drain errors or water returning to the drum may point to a pump, sensor or plumbing issue.
When to book a technician
Do not force a locked door. The interlock protects against flooding and high-speed drum movement. Arrange a technician if the emergency release procedure in the manual does not resolve it.
Safety note
Disconnect power where the manufacturer instructs. Do not open sealed electrical or refrigerant systems without proper training.
